Network Administrator

Position: Network Administrator [#5002]
Alteo is looking for a Network Administrator for a permanent job based in Montreal.

*** Remote job from Montreal. Multi-site role with international travel (~10-20%).  Spanish is required  (full professional fluency, spoken and written) since the majority of the team is located in south America. **
* You will be responsible for operating a network infrastructure across multiple sites, including facilities abroad. We're looking for a hands-on Network Administrator / Technician who is as comfortable racking and cabling equipment as configuring it, and who can work directly with our Spanish-speaking site teams — remotely day to day, and on-site during deployments, upgrades, and escalations.

Responsibilities:

Deploy, configure, and maintain multi-site network infrastructure:
Cisco Catalyst switching and routing (VLANs, trunking, STP, LACP, inter-VLAN routing)

Administer pf Sense firewalls: rulesets, NAT, site-to-site and remote-access VPNs (IPsec/OpenVPN/Wire Guard), high availability

Build and maintain Proxmox VE hosts and clusters: VM/container provisioning, storage, backups, virtual networking

Troubleshoot end to end — from the physical layer (cabling, optics, hardware) through switching, routing, and firewall issues — using packet captures, CLI diagnostics, and a structured methodology

Act as the primary technical contact for Spanish-speaking site teams abroad: guide on-site staff through diagnostics and repairs, and write clear procedures and instructions in Spanish

Travel to sites for buildouts, migrations, and escalated incidents

Coordinate with ISPs, vendors, and contractors on circuits, RMAs, and installations

Participate in planned maintenance windows and an on-call rotation

Profile:

3–5 years of hands‑on network administration or senior technician experience in enterprise environments

Proficiency in Spanish is a must  since you will interact with a latin american team on a day to day basis

Solid Cisco IOS experience on Catalyst platforms (switching required, routing fundamentals expected)

Production experience administering pf Sense (or comparable firewall platforms)

Experience running Proxmox VE (or comparable hypervisors) in production

Strong, methodical troubleshooting skills — able to isolate faults quickly under pressure and communicate status clearly

Full professional fluency in Spanish, spoken and written, including technical vocabulary

Valid passport and ability to travel internationally, occasionally on short notice

Nice to have:

CCNA or CCNP

OPNsense, VyOS, Mikro Tik, or other open‑source/alternative network platforms

Structured cabling and fiber experience (terminations, optics/DACs, testing)

Spreadsheet (Excel, grist, airtable)

Monitoring and documentation tooling:
Zabbix, LibreNMS, Grafana, Net Box, Data Gerry

Datacenter or industrial site experience
